well i'm not sure but maybe

awk '{print $NF}' file

A small change will do the work :

sed 's/\(.*\)\(x[^ ]*\)\(.*\)/\1\3/'

Thanks a lot Panyam..it worked perfect.

sed 's/\(.*\)\(x[^ ]*\)\(.*\)/\1\3/' file_name.txt

so this....

sed 's/x[a-z]*[0-9]*//g'

this code also works but only if the word contain numbers or literals.
Thank you

sed 's/\<x[^ ]*//g'
